I am in the process of upgrading from a 125 gallon saltwater aquarium with a canister filter (fish only) to a 150 gallon with a sump (fish and coral). I have a few questions about flow of sump pump required to support this and also size (diameter) of return line and if I should use the Herbie or Durso overvflow. My biggest concern is that I'm set up to make sure I don't have an overflow in the event of a power outage.
Thanks for any help.
